RESUMO
AIM: To analyze the clinical effects of preoperative intravitreal Conbercept combined vitrectomy for proliferative diabetic retinopathy ( PDR) patients.?METHODS:From June 2014 to May 2017, 57 patients (65 eyes) diagnosed with PDR. The patients were divided into two groups according to whether received preoperative intravitreal conbercept: intravitreal group ( 27 cases, 31 eyes), control group (30 cases, 34 eyes). Intravitreal group was treated with 0. 05mg ( 0. 05mL ) conbercept intravitreal injection 3d before vitrectomy, while control group was treated with vitrectomy alone. The overall surgical time, intraoperative bleeding, use of endodiathermy, iatrogenic retinal hole, and silicone oil, postoperative vitreous hemorrhage and the best corrected visual acuity were recorded and analyzed.?RESULTS: The average surgical time of intravitreal group was lower ( P < 0. 05 ), while intraoperative hemorrhage rate, rate of endodiathermy application, iatrogenic hiatal incidence, rate of silicone oil application, incidences of recurrent vitreous hemorrhage of intravitreal group were lower than those of control group ( all P<0. 05 ) . Intravitreal group got better postoperative best corrected visual acuity than control group (P<0. 05).?CONCLUSION: Intravitreal conbercept for proliferative diabetic retinopathy before 25G vitrectomy decreased surgical complications, reduced the surgical time and postoperative vitreous hemorrhage, and improved the potoperative best corrected visual acuity.
RESUMO
Objective To compare the safety and efficacy of 23-Gauge pars plana vitrectomy (PPV) and PPV combined with scleral buckling-PPV (SB-PPV) in proliferative rhegmatogenous retinal detachments with inferior breaks.Methods Retrospectively nonrandomized clinical case study was conducted in 70 patients with proliferative rhegmatogenous retinal detachment associated with inferior breaks between January 2013 and December 2016,including 39 eyes receiving SB-PPV procedures as the SB-PPV group and 31 eyes undergoing PPV procedures as the PPV group.And anatomical success rate for one procedure,lens trauma rate,retinotomy rate,postoperative best corrected visual acuity (BCVA) outcome and intraocular pressure (IOP) were recorded and analyzed.Results The anatomical success rate for one procedure was 92.3％ (36/ 39) in the SB-PPV group and 74.2％ (23/31) in the PPV group,and the difference was statistically significant (P ＜ 0.035).The lens trauma rate was 2.6％ (1/39) in the SB-PPV group and 19.4％ (6/31) in PPV group,with the difference being statistically significant (P ＜0.05).The retinotomy rate was 5.1％ (2/39) in the SB-PPV group and 32.3％ (10/31) in the PPV group,and the difference approached statistically significance (P ＜0.05).There was no significant difference in the postoperative BCVA and IOP between the two groups (both P ＞ 0.05).Conclusion SB-PPV can increase the anatomical success rate for one procedure in patients with rhegmatogenous retinal detachment associated with inferior breaks,and reduce retinotomy rate and lens trauma rate.
RESUMO
AIM: To investigate the feasibility and clinical effect of punctoplasty by using trabeculectomy punch combined with a novel RS tube for the treatment of punctal stenosis.METHODS: Totally 39 patients (39 eyes) with punctual stenosis were selected from October 2013 to October 2015 in the Second People`s Hospital of Foshan.All patients underwent punctoplasty by using trabeculectomy punch combined with a novel RS tube.These tubes were removed at 3mo after operation.A follow-up of 6mo was taken for final analysis.The fluorescein dye disappearance test score was recorded before the operation and at 1,3 and 6mo after the extubation.The curative effect of the operation at 6mo after the extubation was assess.RESULTS: Fluorescein dye disappearance test: the scores at 1,3 and 6mo after the extubation all decreased compared with the preoperative ones.The difference was statistically significant(P<0.05).At the last following up, 35 eyes (90%) were cured completely, 4 eyes (10%) were improved significantly, no patients recurred.Effective rate was 100%.No serious intraoperative and postoperative complications happened.CONCLUSION: Punctoplasty by using trabeculectomy punch combined with novel RS tubes is a safe and effective method for the punctul stenosis, which is easy to perform, with high success rate.
RESUMO
@#AIM: To study the application of intravitreal injection of anti-vascular endothelial growth factor(VEGF)inpatients with fundus neovascularization disease in No.2 Foshan People's Hospital between 2013 to 2015. <p>METHODS: Retrospective analysis of inpatients of Foshan Second People's Hospital from January 2013 to December 2015, searched the inpatient management system with the term "intravitreal injection", excluded patients with intravitreal injection of TA and antibiotics, and queried the diseases involved. Then summarized the amount of inpatients of each disease as comparison. <p>RESULTS: Totally 239 eyes underwent injection in 3a. The proportion of male and female was even. No statistical difference among the youth,the middle age and the old group. The amount of injections was increased year by year. The main diseases underwent anti-VEGF injection was retinal vein occlusion(RVO), choroidal neovascularization retinopathy(CNV), diabetic retinopathy(DR)and polypoidal choroidal vasculopathy(PCV). Anti-VEGF injection ratio(injection/total)of the four diseases in the same year and each disease of different year were significantly statistic different. Among the four main disease, anti-VEGF injection was the most accepted in CNV patients, and anti-VEGF injection ratio was the most improved in PCV patients. <p>CONCLUSION: Anti-VEGF intravitreal injection as a new treatment for fundus neovascular diseases was increasingly accepted by patients.
